Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to a stamping mold for flanging automobile crossbeams. Background Technology

[0002] Molds, as various shapes and tools used in industrial production to obtain desired products through injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, and other methods, play an indispensable and crucial role in many manufacturing fields. Among them, the automotive crossbeam flanging stamping die is a specialized tooling fixture in the automotive manufacturing industry specifically designed to achieve the "flanging" process and integral stamping forming of the key structural component, the "automotive crossbeam." Utilizing the mechanical force and specific cavity structure of the mold, it processes flat or pre-formed metal sheets (such as high-strength steel) into finished automotive crossbeams with flanging features that meet design requirements, either in one step or in stages. It is a key piece of equipment for the mass production of core components of the automotive body chassis.

[0003] With the booming development of the automotive industry, the pace of product updates is accelerating, and different models and specifications of automobiles have significant differences in the size, shape, and flanging requirements of crossbeams. This requires automotive crossbeam flanging stamping dies to be able to flexibly adapt to diverse production needs and have the ability to quickly change key components to produce automotive crossbeams of different specifications.

[0004] However, in existing technologies, most automotive crossbeam flanging stamping dies use a fixed mounting method for the upper punch and lower die. While this mounting method ensures the stability and rigidity of the die structure to a certain extent, it also brings many drawbacks. When different specifications of automotive crossbeams need to be produced, because the upper punch and lower die are difficult to disassemble and replace quickly, companies often need to invest a lot of money to purchase multiple sets of dies of different specifications. This not only increases production costs but also occupies a large amount of production space and storage space.

[0005] Therefore, some molds are designed with detachable structures. However, existing disassembly methods are complex, require various specialized tools, and are time-consuming. In actual production, frequent mold changes severely impact production efficiency, leading to excessive downtime on the production line and failing to meet the demands of large-scale, high-efficiency automobile production. Utility Model Content

[0006] The main purpose of this utility model is to provide a stamping die for flanging automotive crossbeams, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A stamping die for flanging automotive crossbeams includes an upper die base and a lower die base. An upper punch is mounted on the bottom of the upper die base, and a lower die is mounted on the top of the lower die base. A hydraulic cylinder is fixedly mounted on the top of the upper die base.

[0009] The upper punch and lower die are respectively detachably mounted on the upper die base and the lower die base;

[0010] Two strip grooves are respectively opened on the opposite surfaces of the upper mold base and the lower mold base. Two movable blocks are slidably installed in the grooves. A plug rod is fixedly connected to one side of each movable block. A plug block is installed on the opposite surface of the upper punch and the lower die. The plug rod is inserted into the plug block installed on the opposite surface of the upper punch and the lower die. Two movable grooves are opened on the opposite surfaces of the upper mold base and the lower mold base. An adjustment plate that cooperates with the movable block is provided in the movable groove. A pusher is provided on one side of the adjustment plate for controlling the horizontal movement of the adjustment plate and moving the two movable blocks toward each other.

[0011] Preferably, the pushing component includes a screw, and the upper mold base and the lower mold base have screw holes on both sides that communicate with the movable groove. The screw is threadedly connected to the screw holes. A knob is fixedly connected to one end of the screw, and a rotating block is fixedly connected to the other end of the screw. A groove is provided on the side of the adjusting plate near the screw hole, and the rotating block is rotatably connected to the groove.

[0012] Preferably, the two sides of the adjusting plate are fixedly connected with first slide bars, and the first slide bars are slidably connected to the first slide grooves opened on both sides of the movable groove.

[0013] Preferably, the top surface of the adjustment plate has two adjustment grooves, which are V-shaped.

[0014] Preferably, an adjusting rod is fixedly connected to the top of the movable block, the adjusting rod is inserted into the adjusting groove, and second sliding bars are fixedly connected to both sides of the movable block. The second sliding bars are slidably connected to the second sliding grooves opened on both sides of the strip groove, and the strip groove and the movable groove are interconnected.

[0015] Preferably, the four corners of the opposite surfaces of the upper punch and the lower die are respectively fixedly connected with insert blocks, the insert blocks are inserted into the strip groove, and the side wall of the insert block is provided with an insertion hole for insertion with the insert rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] By detachably mounting the upper punch and lower die on the upper and lower die bases respectively, when producing different specifications of automotive crossbeams, it is only necessary to control the horizontal movement of the adjusting plate by pushing the component. This allows the strip groove to drive the two movable blocks to slide towards each other through the adjusting rod inside the groove. This allows the insertion state of the insert rod on the movable block to quickly switch with the insertion block on the upper punch and lower die. When the insert rod disengages from the insertion hole, the old upper punch or lower die can be directly removed. After replacing the new forming part, the operation can be reversed to complete the fixing. This achieves rapid disassembly and replacement of the upper punch and lower die, which is simple to operate and does not require a variety of professional tools. It effectively shortens the mold change time, improves production efficiency, and reduces production costs. At the same time, it avoids damage to the mold caused by the complex disassembly process, extends the mold service life, and can better adapt to the production needs of different specifications of automotive crossbeams.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1 - Figure 6As shown, a stamping die for flanging an automobile crossbeam includes an upper die base 1 and a lower die base 2. An upper punch 3 is installed at the bottom of the upper die base 1, and a lower die 4 is installed at the top of the lower die base 2. A hydraulic cylinder 5 is fixedly installed at the top of the upper die base 1. The mounting end of the hydraulic cylinder 5 is fixed to an external bracket, and the output end is fixed to the upper die base 1. This allows the hydraulic cylinder 5 to drive the output end to push the upper die base 1 to move vertically, so that the upper punch 3 completes the flanging stamping of the automobile crossbeam during the process of closing with the lower die 4 at the top of the lower die base 2.

[0027] The upper punch 3 and the lower die 4 are respectively detachably mounted on the upper die base 1 and the lower die base 2;

[0028] Two strip grooves 11 are respectively opened on the opposite surfaces of the upper mold base 1 and the lower mold base 2. Two movable blocks 20 are slidably installed in the grooves 11. A plug rod 23 is fixedly connected to one side of the movable block 20. A plug block 6 is installed on the opposite surface of the upper punch 3 and the lower die 4. The plug rod 23 is inserted into the plug block 6 installed on the opposite surface of the upper punch 3 and the lower die 4. Two movable grooves 8 are opened on the opposite surfaces of the upper mold base 1 and the lower mold base 2. An adjustment plate 16 that cooperates with the movable block 20 is provided in the movable groove 8. A pusher is provided on one side of the adjustment plate 16 for controlling the horizontal movement of the adjustment plate 16 and moving the two movable blocks 20 toward each other.

[0029] like Figure 3 - Figure 6 As shown, the pushing component includes a screw 13. Screw holes 10 communicating with the movable groove 8 are provided on both sides of the upper mold base 1 and the lower mold base 2. The screw 13 is threadedly connected to the screw holes 10. A knob 14 is fixedly connected to one end of the screw 13, and a rotating block 15 is fixedly connected to the other end of the screw 13. A groove 17 is provided on the side of the adjusting plate 16 near the screw holes 10. The rotating block 15 is rotatably connected to the groove 17. Because the screw 13 is threadedly connected to the screw holes 10 on both sides of the upper mold base 1 and the lower mold base 2, the threaded engagement converts the rotational movement of the knob 14 into a horizontal linear movement of the screw 13 along the axis of the screw holes 10. Simultaneously, the rotating block 15 at the other end of the screw 13 is embedded in the adjusting plate. The adjusting plate 16 is located in the groove 17 on one side of the screw 13, and the rotating block 15 can rotate freely in the groove 17. This prevents the adjusting plate 16 from rotating synchronously when the screw 13 rotates. It can only push or pull the adjusting plate 16 to move horizontally along the movable groove 8. No special tools are needed. The movement of the adjusting plate 16 can be controlled by manually rotating the knob 14. The ease of operation is greatly improved, and the dependence on the operator's skills is reduced. Moreover, the threaded transmission has "self-locking". After the screw 13 is engaged with the screw hole 10, the adjusting plate 16 will not move on its own without external force to rotate the knob 14. This ensures that the position of the adjusting plate 16 is stable during the stamping process and prevents the insertion relationship between the insert rod 23 and the insert block 6 from becoming loose.

[0030] like Figure 3 - Figure 6As shown, first slide bars 18 are fixedly connected to both sides of the adjusting plate 16. The first slide bars 18 are slidably connected to the first slide grooves 9 opened on both sides of the movable groove 8. When the adjusting plate 16 moves horizontally under the action of the pushing member, the first slide bars 18 will slide synchronously along the trajectory of the first slide grooves 9. The cooperation between the first slide bars 18 and the first slide grooves 9 forms a "guiding constraint" on the movement direction of the adjusting plate 16, restricting the adjusting plate 16 to only move along the length direction of the first slide grooves 9, and preventing vertical offset or horizontal tilt. This avoids misalignment between the V-shaped adjusting groove 19 and the adjusting rod 22 due to offset when the adjusting plate 16 moves, and ensures that the adjusting plate 16 can stably drive the movable block 20 to move.

[0031] like Figure 5 and Figure 6 As shown, the top surface of the adjusting plate 16 has two adjusting grooves 19, which are V-shaped. When the adjusting plate 16 moves horizontally, the side walls of the adjusting grooves 19 will generate a lateral thrust on the adjusting rod 22. Since the adjusting grooves 19 are V-shaped, their side walls form an angle with the direction of movement of the adjusting plate 16. This thrust will be decomposed into a component force that drives the two movable blocks 20 to "approach each other" or "move away from each other". When the adjusting plate 16 moves towards the screw hole 10, the groove walls of the V-shaped adjusting grooves 19 push the adjusting rod 22, causing the two movable blocks 20 to slide towards each other along the strip groove 11, and vice versa.

[0032] like Figure 3 - Figure 5 As shown, an adjusting rod 22 is fixedly connected to the top of the movable block 20. The adjusting rod 22 is inserted into the adjusting groove 19. Second sliding strips 21 are fixedly connected to both sides of the movable block 20. The second sliding strips 21 are slidably connected to the second sliding grooves 12 opened on both sides of the strip groove 11. The strip groove 11 and the movable groove 8 are interconnected. When the movable block 20 moves under the action of the adjusting rod 22, the second sliding strips 21 slide along the second sliding grooves 12. The cooperation between the second sliding strips 21 and the second sliding grooves 12 restricts the movable block 20 to move only along the length direction of the strip groove 11, preventing the movable block 20 from deflecting or jumping up and down during the sliding process, and ensuring that the insertion rod 23 on one side of the movable block 20 can be accurately aligned with the insertion hole 7 of the insertion block 6.

[0033] like Figure 2 , Figure 3 and Figure 5As shown, the four corners of the opposite faces of the upper punch 3 and the lower die 4 are respectively fixedly connected with insert blocks 6. The insert blocks 6 are inserted into the strip groove 11. The side wall of the insert block 6 is provided with insertion holes 7 for insertion rod 23. During installation, it is directly inserted into the strip groove 11 of the upper die base 1 and the lower die base 2. The strip groove 11 forms a preliminary positioning for the insert block 6. Then, the movable block 20 drives the insert rod 23 to move, so that the insert rod 23 is inserted into the insertion hole 7 on the side wall of the insert block 6. Through the insertion and cooperation of the insert rod 23 and the insertion hole 7, the insert block 6 is fixed in the strip groove 11, thereby realizing the fixation of the upper punch 3 to the upper die base 1 and the lower die 4 to the lower die base 2. During disassembly, the movable block 20 drives the insert rod 23 to disengage from the insertion hole 7, so that the insert block 6 can be removed from the strip groove 11, completing the disassembly of the upper punch 3 or the lower die 4.

[0034] The specific operating principle of this automotive crossbeam flanging stamping die is as follows:

[0035] When the automobile crossbeam flanging stamping forming die is working, the hydraulic cylinder 5 is started, and its output end drives the upper die base 1 to move vertically downward, so that the upper punch 3 installed at the bottom of the upper die base 1 and the lower die 4 installed at the top of the lower die base 2 close together, and perform flanging stamping forming operation on the metal sheet placed between the two.

[0036] When it is necessary to change the upper punch 3 or lower die 4 of different specifications, rotate the knobs 14 on both sides of the upper die base 1 and the lower die base 2. The knobs 14 drive the screw 13 to rotate in the screw hole 10. Since the rotating block 15 at one end of the screw 13 is rotatably connected to the groove 17 on the adjusting plate 16, the rotation of the screw 13 will push the adjusting plate 16 to move horizontally. The first slide bars 18 on both sides of the adjusting plate 16 slide in the first slide grooves 9 on both sides of the movable groove 8 to ensure the stability of the movement of the adjusting plate 16. The V-shaped adjusting groove 19 on the top surface of the adjusting plate 16 moves accordingly, driving the adjusting rod 22 inserted in the adjusting groove 19 to move. The adjusting rod 22 drives the movable block 20. Sliding within the strip groove 11, the second sliding strips 21 on both sides of the movable block 20 slide within the second sliding grooves 12 on both sides of the strip groove 11, making the movement of the movable block 20 more stable. The movement of the movable block 20 drives the insertion rod 23 on one side to be pulled out from the insertion hole 7 on the side wall of the insertion block 6. At this time, the old upper punch 3 or lower die 4 can be removed, and the insertion blocks 6 at the four corners of their opposite surfaces can be pulled out from the strip groove 11. After replacing the new upper punch 3 or lower die 4, insert the insertion block 6 into the strip groove 11, and rotate the knob 14 in the opposite direction to make the insertion rod 23 re-insert into the insertion hole 7, completing the installation and fixing of the new part, and then proceeding with the subsequent processing of different specifications of automotive crossbeams.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components can be replaced with equivalents or some technical features can be replaced with equivalents. All such improvements within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
